Bug?? - Shaped windows etc.

[Anonymous]

When I use a window with an arched (or trapezoid, or anything that uses RISE
in the dialog box) head, it is not drawn the way I think it should be.
For instance, with an arched window, 1410 wide, if I specify a head height
of 2460, and a rise of 250, I would expect that the apex of the arch is at
2460, and the "shoulder" to be at 2210. BUT the "shoulder" is at 2187.93. To
get the shoulder to be 2210, I've got to use trial and error and end up with
the rise set at round 229.26.
I've just tried changing the window style to peaked and trapezoid, and for
each different style, the rise required is different, AND even the head
height that is set at 2460, is drawn at a different height for each style.
To me, this is quite serious. If I want to insert a window with a raking
head of say 25 degrees, I use the window width x tan 25degrees to get the
rise, but when the window is inserted it comes out wrong.

I've done a search of the newsgroup with no sign of this problem being
mentioned. I find it hard to believe that I'm the only person to notice
this.

Thanks,

Chris,

I've noticed that the rise is figured from the inside of the frame even
when you're figuring window openings from the outside.  I've just
gotten into the habit of subtracting my frame width from the overall width
and figuring the rise from there.  Seems to work then.
